پرامپت ویدیو نمای ساختمان با ابر و نور گذرا

The input image is the first frame. A locked-off time-lapse of the building. Keep the building exactly as in the image: same architecture, facade, floors, windows, balconies, signage and surroundings, with no new floors, structures or features. Clouds stream quickly across the sky, shadows glide across the facade, and the light shifts like this: از عصر آفتابی به غروب طلایی; window lights switch on one by one in the last three seconds and the final frame rests on the lit building. Static tripod camera, no camera movement. Mood: confident, aspirational, calm. Audio: a soft ambient pulse that rises with the light, distant city hum and a far-off bird, a warm final chord, no dialogue. No added text, no captions, no watermark.
